摘　　要：本文阐述了九龙江河口 ＳＤ０３孔 ３１个主要硅藻种的分布特征，并把该孔细分为３个硅藻段、９个硅藻带且结合^(１４)Ｃ测年资料进行了地层的划分。结果表明，该孔全长３６ｍ的沉积物属于全新世沉积，全新世海面在总体上升的过程中，约在８ｋａ，Ｂ．Ｐ．发生过短暂的下降。Based on the distributive characteristics of 31 main diatom species in Core SD03 from the Jiulongjiang Estuary, 3 diatom sections and 9 diatom zones are subdivided and the stratigraphical divisions are made in the core combined with ~14C datings. The results show that the core (36m long) belongs to Holocene sediments and a temporal falling occurred at about 8ka. B. P. in the total rising course of the Holocene sealevel.
